Tomcat Java.lang.outofmemoryerror: Java Heap Space
only takes a minute: Sign up java out of memory error-heap space up vote 2 down vote favorite 1 I'm developing web application in jsp/servlet,i had an issue with netbeans and Java. My program needs large data process. So I used -Xmx512m to increase the maximum heap size via Tools -> Servers -> on the Platform tab there is a java.lang.outofmemoryerror thrown from the uncaughtexceptionhandler in thread "main" VM option below Java Platform. Then it works fine.. Now my issue is i'm building the WAR file, directly deployed and run in my another machine Tomcat for demo, here i'm facing the same issue java out of memory error-heap space i also tried with environment variable set CATALINA_OPTS=-Xms512m -Xmx512m this also didn't help me how to resolve this issue?, Please point me to the right direction java tomcat out-of-memory share|improve this question asked Sep 11 '12 at 9:47 Sathish 1,67131642 1 Make it -Xmx1024m and try again. –duffymo Sep 11 '12 at 9:49 where in the environment variable? –Sathish Sep 11 '12 at 9:50 Edit the start script. –duffymo Sep 11 '12 at 9:53 Finally i found the solution for the issue see my answer below –Sathish Sep 11 '12 at 11:15 add a comment| 3 Answers 3 active oldest votes up vote 9 down vote Try to set PermSizeand MaxPermSize values. and that should be set at tomcat startup in Catalina.bat and then stop and start using this script.
space Cause and Solution Tomcat web server often suffers from java.lang.OutOfMemoryError: PermGen space whenever you deploy and un-deploy your web application couple of time. No matter you are using tomcat6, tomcat7 or using bundled tomcat in Netbeans or Eclipse http://javarevisited.blogspot.com/2012/01/tomcat-javalangoutofmemoryerror-permgen.html you will face this error now and then while developing web application on tomcat https://newfivefour.com/tomcat7-heap-dump-out-of-memory.html server. I thought about this article after writing 2 Solution of OutOfMemoryError in Java. I have touched this issue there but then I thought to write a separate tutorial for tomcat outofmemoryerror because I am getting this error too frequently. In this article, we will see what causes java.lang.OutOfMemoryError: PermGen Space in tomcat and how to fix out of java.lang.OutOfMemoryError: PermGen Space in tomcat server. Tomcat - java.lang.OutOfMemoryError: PermGen space Cause and Solution Cause of OutOfMemoryError in PermGen space in Tomcat: PermGen Space of the heap is used to store classes and Metadata about classes in Java. When a class is loaded by a classloader it got stored in PermGen space, it gets unloaded only when the classloader which loaded this class got garbage collected. If any object retains reference out of memory of classloader than it's not garbage collected and Perm Gen Space is not freed up. This causes a memory leak in PermGen Space and eventually cause java.lang.OutOfMemoryError: PermGen space. Another important point is that when you deploy your web application a new Classloader gets created and it loads the classes used by the web application. So if Classloader doesn't get garbage collected when your web application stops you will have a memory leak in tomcat. Solution of Tomcat: OutOfMemroyError: 1) Find the offending classes which are retaining reference of Classloader and preventing it from being garbage collected. Tomcat provides memory leak detection functionality after tomcat 6 onwards which can help you to find when the particular library, framework or class is causing a memory leak in tomcat. Here are some of the common causes of java.lang.OutOfMemoryError: PermGen space in tomcat server: 1) JDBC Drivers: JDBC drivers are most common cause of java.lang.OutOfMemoryError: PermGen space in tomcat if web app doesn't unregister during the stop. One hack to get around this problem is that JDBC driver to be loaded by common class loader than application classloader and you can do this by transferring driver's jar into tomcat lib instead of bundling it on web application's war file. 2) Logging framework: A similar solution
